Find the square numbers and see which ones 54 lies between 1, 4, 9, 16, 25, 36, 49, 64. It lies between the two square numbers 49 and 64. But you want the square root. So find the square root of 49 and 64. 7 and 8. So the square root of 54 is between 7 and 8. Hope this helps.
If there are no answer choices, I'll give you a few to work with: 16:52 (divide each number by 3 to get this) 8:26 (divide the above by 2, both sides) 4:13 (divide the above by 2, both sides) 96:312 (multiply the original by 2, both sides) I think you get the gist. ~Hope this helps!
